Re: [pcsx-df-devel] Mdec patch for FF9 video

[Mongrove <dot...@gm...>]

Hello, I'm back :)

I fix the mdec bug, in another way, which may be the rigth way.


I log data send to the mdec by DMA0, and I found that the list of
block finish by a lot of 0xFE00 flags where a new block header should
be.

In FF9, the mdec should be busy until all block are decrompressed and
send back by DMA1. Now, the mdec detect the end of list properly and
go back to idle stase after send back the last decompressed block.

Other games don't care that mdec is busy until the last block, where
they check if the mdec is idle :).

I join the mdec.c file :) have fun, I hope that help.
